In chemistry, a dipolar compound or simply dipolar is an electrically neutral molecule carrying a positive and a negative charge in at least one canonical description. In most dipolar compounds the charges are delocalized. Dipolar compounds can be represented by a resonance structure. Contributing structures containing charged atoms are denoted as zwitterions. Some dipolar compounds can have an uncharged canonical form.

Types of dipolar compounds

 * 1,2-dipolar compounds have the opposite charges on adjacent atoms.
 * 1,3-dipolar compounds have the charges separated over three atoms.
 * Betaines are zwitterionic compounds derived from amino acids.
